ABP mode gives an ASSERT on LMIC_setTxData2.

Describe your question or issue

Because of problems with #311 I was trying out ABP mode. I am getting the following error on do_send (from the examples).

~/Arduino/libraries/arduino-lmic-master/src/lmic/radio.c:1065

here

( ttn-abp )

I actually see the message arrive in the dashboard (I updated the do_send to send out some specific data):

Environment

• TRFM95W module.. uses SX1276 I think connected to a blue pill (stm32f108).
• On EU network. 868 MHz. TheThingsNetwork
• GIT version of 2020-06-23.

On a ttgo t3 it does seem to work.

So I am looking at hints to see where the actual problem lies?

The radio should automatically drop to sleep mode after a successful tx. It's not. So ... looks like a hardware problem to me.

thx, was afraid of that. I am going to try another module.
